RE: https://forum.techinferno.com/apple-egpu-discussion/8558-%5Bguide%5D-macbook-enabling-optimus-internal-lcd-mode.html Hi I did all of this, and know I can't even use my egpu. When I boot up windows without disabling my GT750M (mbpr 15" 2013), Device Manager gives me a code 12 for my gtx 970 card, "This device doesn't have enough resources blabla..". When I disable my GT750m windows freezes at booting at the "dots" circling around... Before i could actually use the egpu with an external display, but now I can't do anything. Can you please help? Thank you for your time
